Effect of Expiratory Muscle Strength in Patients With Bronchiectasis

This study aims to examine the relationship between expiratory muscle strength and clinical outcomes such as disease severity, hospital admission history, and quality of life in individuals with bronchiectasis. Effective coughing is a critical physiological reflex for airway clearance; however, the relationship between expiratory muscle strength and cough effectiveness in the bronchiectasis population has not been clearly established. Identifying expiratory muscle weakness as a potential contributor to increased symptom burden and impaired airway clearance may improve clinical understanding and support the development of targeted physiotherapy interventions. The findings of this study could serve as a foundation for future interventional research in pulmonary rehabilitation and respiratory muscle training for this population.
